More than 40 value-based payment models – from direct contracting to bundled payments – have been introduced into the Medicare program in the past 10 years, with the goal of improving care while lowering costs. Hopes were high that they would be successful.

But despite the new alternative payment models, costs have not declined. If this continues, Medicare won’t have sufficient funds to cover benefit costs after 2024. Physicians could suffer a huge blow to their income.

Many of the value-based care models simply did not work as expected, said Seema Verma, head of the Centers for Medicare & Medicaid Services, at a recent HLTH Conference. “They are not producing the types of savings the taxpayers deserve,” Ms. Verma said.

The Medicare Payment Advisory Commission (MedPac) concluded that, while dozens of payment models were tested, most failed to generate net savings for Medicare. Even the most successful of the models produced only modest savings. MedPac elaborated: “The track record raises the question of whether changes to particular models or CMMI’s [Center for Medicare & Medicaid Innovation’s] broader strategies might be warranted.”

What will happen now, as government officials admit that their value-based programs haven’t worked? The value-based programs could become more stringent. Here’s what physicians will have to contend with.

More risk. Experts agree that risk – financial risk – will be a component of future programs. Two-sided risk is likely to be the norm. This means that both parties – the provider and the insurer – are at financial risk for the patients covered by the program.

For example, a plan with 50,000 beneficiary patients would estimate the cost of caring for those patients on the basis of multiple variables. If the actual cost is lower than anticipated, both parties share in the savings. However, both share in the loss if the cost of caring for their patient population exceeds expectations.

This may compel physicians to enhance efficiency and potentially limit the services provided to patients. Typically, however, the strategy is to make efforts to prevent services like ED visits and admissions by focusing on health maintenance.

In contrast to most current value-based models, which feature little to no downside risk for physicians, double-sided risk means physicians could lose money. The loss may incorporate a cap – 5%, for example – but programs may differ. Experts concur that double-sided risk will be a hallmark of future programs.

Better data. The majority of health care services are rendered via fee-for-service: Patients receive services and physicians are paid, yet little or no information about outcomes is exchanged between insurers and physicians.

Penny Noyes, president of Health Business Navigators and contract negotiator for physicians, is not a fan of the current crop of value-based programs and feels that data transparency is positive. Sound metrics can lead to improvement, she said, adding: “It’s not money that drives physicians to make decisions; it’s what’s in the best interest of their patients and their patients’ long-term care.”

Value-based programs can work but only if applicable data are developed and given to physicians so that they can better understand their current performance and how to improve.

Mandated participation. Participation in value-based programs has been voluntary, but that may have skewed the results, which were better than what typical practice would have shown. Acknowledging this may lead CMS to call for mandated participation as a component of future programs. Physicians may be brought into programs, if only to determine whether the models really work. To date, participation in the programs has been voluntary, but that may change in the future.

Innovation. The private insurance market may end up as a key player. Over the past 6 months, health insurers have either consolidated partnerships with telemedicine companies to provide no-cost care to beneficiaries or have launched their own initiatives.

Others are focused on bringing together patients and providers operating outside of the traditional health care system, such as Aetna’s merger with CVS which now offers retail-based acute care (MinuteClinic) and chronic care (HealthHUB). Still other payers are gambling with physician practice ownership, as in the case of United Healthcare’s OptumHealth, which now boasts around 50,000 physicians throughout the country.

New practice models are emerging in private practices as well. Physicians are embracing remote care, proactively managing care transitions, and seeking out more methods to keep patients healthy and at home.
 

Not much was expected from value-based plans 

Many are not surprised that the value-based models did not produce impressive results. Ms. Noyes doubted that positive outcomes will be achieved for physicians in comparison with what could have been attained under fee-for-service arrangements with lower administrative costs.

While the Affordable Care Act attempted to encourage alternative reimbursement, it limits the maximum medical loss ratio (MLR) a payer could achieve. For many plans, that maximum was 85%. Simply put, at least $0.85 of each premium collected had to be paid in claims; the remaining $0.15 went to margin, claims, and other administrative costs. A payer with an 82% MLR then would have to rebate the 3% difference to enrollees.

But that’s not what occurred, according to Ms. Noyes. Because value-based payments to providers are considered a claims expense, an MLR ratio of 82% allowed the payer to distribute the 3% difference to providers as value-based payments. Ms. Noyes said: “That may sound good for the provider, but the result was essentially a freeze on the provider’s fee-for-service reimbursement with the prospect of getting value-based payments like ‘shared savings.’ 

“When the providers tried to increase their base fee-for-service rates just to match inflation, payers often advised that any future raises had to be earned through value-based programs,” Ms. Noyes added. The value-based formulas confuse providers because payments are often made for periods as far back as 18 months, and providers do not have data systems to reconcile their payer report cards retrospectively. The result is that providers tended to accept whatever amount the payer distributed.

Executives at Lumeris, a company that helps health systems participate successfully in value-based care, see potential in a newer approach to alternative payments, such as CMS’ Direct Contracting initiative. This voluntary payment model offers options tailored to several types of organizations that aim to reduce costs while preserving or enhancing the quality of care for Medicare fee-for-service beneficiaries.

Jeff Smith, chief commercial officer for population health at Lumeris, explained that the Direct Contracting initiative can provide physicians with a more attractive option than prior value-based models because it adjusts for the complexity and fragility of patients with complex and chronic conditions. By allowing providers to participate in the savings generated, the initiative stands in stark contrast to what Mr. Smith described as the “shared savings to nothingness” experienced by providers in earlier-stage alternative payment models.

Physicians engaged with value-based programs like Direct Contracting are investing in nurses to aid with initiatives regarding health promotion and transitions of care. When a patient is discharged, for example, the nurse contacts the patient to discuss medications, schedule follow-up appointments, and so forth – tasks typically left to the patient (or caregiver) to navigate in the traditional system.

The initiative recognizes the importance of managing high-risk patients, those whom physicians identify as having an extraordinary number of ED visits and admissions. These patients, as well as so-called “rising-risk” patients, are targeted by nurses who proactively communicate with patients (and caregivers) to address patient’s needs, including social determinants of health.

Physicians who have a large load of patients in value-based programs are hiring social workers, pharmacists, and behavioral health experts to help. Of course, these personnel are costly, but that’s what the value-based programs aim to reimburse.

Still, the road ahead to value based is rocky and may not gain momentum for some time. Johns Hopkins University’s Doug Hough, PhD, an economist, recounts a government research study that sought to assess the university’s health system participation in a value-based payment program. While there were positive impacts on the program’s target population, Hough and his team discovered that the returns achieved by the optional model didn’t justify the health system’s financial support for it. The increasingly indebted health system ultimately decided to drop the optional program.

Dr. Hough indicated that the health system – Johns Hopkins Medicine – likely would have  continued its support for the program had the government at least allowed it to break even. Although the payment program under study was a 3-year project, the bigger challenge, declared Dr. Hough, is that “we can’t turn an aircraft carrier that quickly.”

“Three years won’t show whether value-based care is really working,” Dr. Hough said.

Robert Zipper, MD, a hospitalist and senior policy advisor for Sound Physicians, a company that works to improve outcomes in acute care, agreed with Dr. Hough that performance tends to improve with time. Yet, Dr. Zipper doesn’t see much change in the near term, because “after all, there is nothing to replace them [the programs].”

The problem gets even stickier for private payers because patients may be on an insurance panel for as little as a year or 2. Thanks to this rapid churn of beneficiaries, even the best-designed value-based program will have little time to prove its worth.

Dr. Zipper is among the many who don’t expect significant changes in the near term, asserting that “President Biden will want to get a few policy wins first, and health care is not the easiest place to start.”

But it’s likely that payers and others will want to see more emphasis on value-based programs despite these programs’ possible value to patients, physicians, and health systems alike.

The beneficial effects of sacubitril/valsartan on reverse cardiac remodeling in patients with heart failure and reduced ejection fraction have been well established, but those benefits haven’t been as clearly demonstrated to carry over to HFrEF patients who also have type 2 diabetes mellitus (T2DM).

Now, a post-hoc analysis of a pivotal clinical trial reports that those benefits do extend to patients with HFrEF and T2DM.

“It’s really not about a Sophie’s choice of whether you give this or that drug in these patients,” said corresponding author Javed Butler, MD, MPH, MBA. “We really ought to be giving all of these drugs – the angiotensin receptor neprilysin inhibitors (ARNIs) and sodium-glucose transporter 2 (SGLT-2) inhibitors – to our patients for the best outcomes.”

The post-hoc analysis, published in JACC: Heart Failure, evaluated 361 patients with T2DM who were enrolled in the PROVE-HF trial of sac/val therapy for HF, published in JAMA.

PROVE-HF evaluated biomarkers, myocardial remodeling, and outcomes through a year of treatment with sac/val. The primary endpoint was the level of changes in natriuretic peptide (NT-proBNP) concentrations, left-ventricle ejection fraction (LVEF) and overall Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 scores through 12 months of treatment.

The post hoc study reported that baseline NT-proBNP concentrations were higher in the DM patients (854 pg/mL vs. 706 pg/mL), but at 12 months those levels were 513 and 441 pg/mL, respectively.

LVEF changed similarly from baseline to 12 months in both groups: from 28.3% to 37% in the DM patients and from 28.1% to 38.34% in non-DM patients. Overall KCCQ-23 scores improved similarly in both groups, but longitudinal analyses found modestly higher gains in the T2DM group, 9.3 vs. 8.6 points (P = .07).

“The real reason I wanted to do this study is that I’m a huge fan of all the SGLT-2 inhibitors, and I’m very involved in those trials, and there is right now so much momentum behind SGLT-2 inhibitors that I don’t want people to forget that ARNI is still the base therapy for HF,” said Dr. Butler, chair of cardiovascular research and the department of medicine at the University of Mississippi in Jackson.

He noted that the size of the diabetes cohort in PROVE-HF “is a nonissue” for evaluating power of the post hoc analysis because it tracked key measures in the study population continuously at eight intervals over the 12 months.

The analysis further demonstrates the synergistic effects of ARNI and SGLT-2 inhibitors in patients with T2DM and HF that were also reported in the PARADIGM-HF study, Dr. Butler said.

“We have sort of moved on, saying that SGLT-2 inhibitors have a benefit on the heart, but the reverse is also true: ARNIs are still heart failure drugs, and we don’t think of them as diabetes drugs, but the PARADIGM-HF data showed that there was a substantial reduction in hemoglobin A1c in those who had diabetes,” he said.

The researchers noted that an absence of a control group may contribute to an overestimation of reverse cardiac remodeling in the T2DM patients, and that the PROVE-HF study wasn’t prospectively powered to delineate differences in how sac/val therapy affected patients with or without diabetes. “Future investigations seeking to evaluate differences by T2DM status after sacubitril/valsartan initiation may use our findings to plan prospective sample sizes,” the researchers wrote.

Dr. Butler disclosed financial relationships with Abbott, Amgen, Array, AstraZeneca, Bayer, Boehringer Ingelheim, CVRx, Eli Lilly, G3 Pharmaceutical, Impulse Dynamics, Innolife, Janssen, Luitpold, Medtronic, Merck, Novartis, Novo Nordisk, Relypsa, Sequana, StealthPeptide and Vifor.

“We have sort of moved on, saying that SGLT-2 inhibitors have a benefit on the heart, but the reverse is also true: ARNIs are still heart failure drugs, and we don’t think of them as diabetes drugs, but the PARADIGM-HF data showed that there was a substantial reduction in hemoglobin A1c in those who had diabetes,” he said.

The researchers noted that an absence of a control group may contribute to an overestimation of reverse cardiac remodeling in the T2DM patients, and that the PROVE-HF study wasn’t prospectively powered to delineate differences in how sac/val therapy affected patients with or without diabetes. “Future investigations seeking to evaluate differences by T2DM status after sacubitril/valsartan initiation may use our findings to plan prospective sample sizes,” the researchers wrote.

The beneficial effects of sacubitril/valsartan on reverse cardiac remodeling in patients with heart failure and reduced ejection fraction have been well established, but those benefits haven’t been as clearly demonstrated to carry over to HFrEF patients who also have type 2 diabetes mellitus (T2DM).

Now, a post-hoc analysis of a pivotal clinical trial reports that those benefits do extend to patients with HFrEF and T2DM.

“It’s really not about a Sophie’s choice of whether you give this or that drug in these patients,” said corresponding author Javed Butler, MD, MPH, MBA. “We really ought to be giving all of these drugs – the angiotensin receptor neprilysin inhibitors (ARNIs) and sodium-glucose transporter 2 (SGLT-2) inhibitors – to our patients for the best outcomes.”

The post-hoc analysis, published in JACC: Heart Failure, evaluated 361 patients with T2DM who were enrolled in the PROVE-HF trial of sac/val therapy for HF, published in JAMA.

PROVE-HF evaluated biomarkers, myocardial remodeling, and outcomes through a year of treatment with sac/val. The primary endpoint was the level of changes in natriuretic peptide (NT-proBNP) concentrations, left-ventricle ejection fraction (LVEF) and overall Kansas City Cardiomyopathy Questionnaire (KCCQ)-23 scores through 12 months of treatment.

The post hoc study reported that baseline NT-proBNP concentrations were higher in the DM patients (854 pg/mL vs. 706 pg/mL), but at 12 months those levels were 513 and 441 pg/mL, respectively.

LVEF changed similarly from baseline to 12 months in both groups: from 28.3% to 37% in the DM patients and from 28.1% to 38.34% in non-DM patients. Overall KCCQ-23 scores improved similarly in both groups, but longitudinal analyses found modestly higher gains in the T2DM group, 9.3 vs. 8.6 points (P = .07).

“The real reason I wanted to do this study is that I’m a huge fan of all the SGLT-2 inhibitors, and I’m very involved in those trials, and there is right now so much momentum behind SGLT-2 inhibitors that I don’t want people to forget that ARNI is still the base therapy for HF,” said Dr. Butler, chair of cardiovascular research and the department of medicine at the University of Mississippi in Jackson.

He noted that the size of the diabetes cohort in PROVE-HF “is a nonissue” for evaluating power of the post hoc analysis because it tracked key measures in the study population continuously at eight intervals over the 12 months.

The analysis further demonstrates the synergistic effects of ARNI and SGLT-2 inhibitors in patients with T2DM and HF that were also reported in the PARADIGM-HF study, Dr. Butler said.

In mid-November, Pfizer/BioNTech were the first with surprising positive protection interim data for their coronavirus vaccine, BNT162b2. A week later, Moderna released interim efficacy results showing its coronavirus vaccine, mRNA-1273, also protected patients from developing SARS-CoV-2 infections. Both studies included mostly healthy adults. A diverse ethnic and racial vaccinated population was included. A reasonable number of persons aged over 65 years, and persons with stable compromising medical conditions were included. Adolescents aged 16 years and over were included. Younger adolescents have been vaccinated or such studies are in the planning or early implementation stage as 2020 came to a close.

These are new and revolutionary vaccines, although the ability to inject mRNA into animals dates back to 1990, technological advances today make it a reality.¹ Traditional vaccines typically involve injection with antigens such as purified proteins or polysaccharides or inactivated/attenuated viruses. mRNA vaccines work differently. They do not contain antigens. Instead, they contain a blueprint for the antigen in the form of genetic material, mRNA. In the case of Pfizer’s and Moderna’s vaccines, the mRNA provides the genetic information to synthesize the spike protein that the SARS-CoV-2 virus uses to attach to and infect human cells. Each type of vaccine is packaged in proprietary lipid nanoparticles to protect the mRNA from rapid degradation, and the nanoparticles serve as an adjuvant to attract immune cells to the site of injection. (The properties of the respective lipid nanoparticle packaging may be the factor that impacts storage requirements discussed below.) When injected into muscle (myocyte), the lipid nanoparticles containing the mRNA inside are taken into muscle cells, where the cytoplasmic ribosomes detect and decode the mRNA resulting in the production of the spike protein antigen. It should be noted that the mRNA does not enter the nucleus, where the genetic information (DNA) of a cell is located, and can’t be reproduced or integrated into the DNA. The antigen is exported to the myocyte cell surface where the immune system’s antigen presenting cells detect the protein, ingest it, and take it to regional lymph nodes where interactions with T cells and B cells results in antibodies, T cell–mediated immunity, and generation of immune memory T cells and B cells. A particular subset of T cells – cytotoxic or killer T cells – destroy cells that have been infected by a pathogen. The SARS-CoV-2 mRNA vaccine from Pfizer was reported to induce powerful cytotoxic T-cell responses. Results for Moderna’s vaccine had not been reported at the time this column was prepared, but I anticipate the same positive results.

The revolutionary aspect of mRNA vaccines is the speed at which they can be designed and produced. This is why they lead the pack among the SARS-CoV-2 vaccine candidates and why the National Institute of Allergy and Infectious Diseases provided financial, technical, and/or clinical support. Indeed, once the amino acid sequence of a protein can be determined (a relatively easy task these days) it’s straightforward to synthesize mRNA in the lab – and it can be done incredibly fast. It is reported that the mRNA code for the vaccine by Moderna was made in 2 days and production development was completed in about 2 months.²

A 2007 World Health Organization report noted that infectious diseases are emerging at “the historically unprecedented rate of one per year.”³ Severe acute respiratory syndrome (SARS), Zika, Ebola, and avian and swine flu are recent examples. For most vaccines against emerging diseases, the challenge is about speed: developing and manufacturing a vaccine and getting it to persons who need it as quickly as possible. The current seasonal flu vaccine takes about 6 months to develop; it takes years for most of the traditional vaccines. That’s why once the infrastructure is in place, mRNA vaccines may prove to offer a big advantage as vaccines against emerging pathogens.
 

Early efficacy results have been surprising

Both vaccines were reported to produce about 95% efficacy in the final analysis. That was unexpectedly high because most vaccines for respiratory illness achieve efficacy of 60%-80%, e.g., flu vaccines. However, the efficacy rate may drop as time goes by because stimulation of short-term immunity would be in the earliest reported results.

Preventing SARS-CoV-2 cases is an important aspect of a coronavirus vaccine, but preventing severe illness is especially important considering that severe cases can result in prolonged intubation/artificial ventilation, prolonged disability and death. Pfizer/BioNTech had not released any data on the breakdown of severe cases as this column was finalized. In Moderna’s clinical trial, a secondary endpoint analyzed severe cases of COVID-19 and included 30 severe cases (as defined in the study protocol) in this analysis. All 30 cases occurred in the placebo group and none in the mRNA-1273–vaccinated group. In the Pfizer/BioNTech trial there were too few cases of severe illness to calculate efficacy.

Duration of immunity and need to revaccinate after initial primary vaccination are unknowns. Study of induction of B- and T-cell memory and levels of long-term protection have not been reported thus far.
 

Could mRNA COVID-19 vaccines be dangerous in the long term?

These will be the first-ever mRNA vaccines brought to market for humans. In order to receive Food and Drug Administration approval, the companies had to prove there were no immediate or short-term negative adverse effects from the vaccines. The companies reported that their independent data-monitoring committees hadn’t “reported any serious safety concerns.” However, fairly significant local reactions at the site of injection, fever, malaise, and fatigue occur with modest frequency following vaccinations with these products, reportedly in 10%-15% of vaccinees. Overall, the immediate reaction profile appears to be more severe than what occurs following seasonal influenza vaccination. When mass inoculations with these completely new and revolutionary vaccines begins, we will know virtually nothing about their long-term side effects. The possibility of systemic inflammatory responses that could lead to autoimmune conditions, persistence of the induced immunogen expression, development of autoreactive antibodies, and toxic effects of delivery components have been raised as theoretical concerns.^4-6 None of these theoretical risks have been observed to date and postmarketing phase 4 safety monitoring studies are in place from the Centers for Disease Control and Prevention and the companies that produce the vaccines. This is a risk public health authorities are willing to take because the risk to benefit calculation strongly favors taking theoretical risks, compared with clear benefits in preventing severe illnesses and death.

What about availability?

Pfizer/BioNTech expects to be able to produce up to 50 million vaccine doses in 2020 and up to 1.3 billion doses in 2021. Moderna expects to produce 20 million doses by the end of 2020, and 500 million to 1 billion doses in 2021. Storage requirements are inherent to the composition of the vaccines with their differing lipid nanoparticle delivery systems. Pfizer/BioNTech’s BNT162b2 has to be stored and transported at –80° C, which requires specialized freezers, which most doctors’ offices and pharmacies are unlikely to have on site, or dry ice containers. Once the vaccine is thawed, it can only remain in the refrigerator for 24 hours. Moderna’s mRNA-1273 will be much easier to distribute. The vaccine is stable in a standard freezer at –20° C for up to 6 months, in a refrigerator for up to 30 days within that 6-month shelf life, and at room temperature for up to 12 hours.

Timelines and testing other vaccines

Strong efficacy data from the two leading SARS-CoV-2 vaccines and emergency-use authorization Food and Drug Administration approval suggest the window for testing additional vaccine candidates in the United States could soon start to close. Of the more than 200 vaccines in development for SARS-CoV-2, at least 7 have a chance of gathering pivotal data before the front-runners become broadly available.

Testing diverse vaccine candidates, based on different technologies, is important for ensuring sufficient supply and could lead to products with tolerability and safety profiles that make them better suited, or more attractive, to subsets of the population. Different vaccine antigens and technologies also may yield different durations of protection, a question that will not be answered until long after the first products are on the market.

AstraZeneca enrolled about 23,000 subjects into its two phase 3 trials of AZD1222 (ChAdOx1 nCoV-19): a 40,000-subject U.S. trial and a 10,000-subject study in Brazil. AstraZeneca’s AZD1222, developed with the University of Oxford (England), uses a replication defective simian adenovirus vector called ChAdOx1.AZD1222 which encodes the SARS-CoV-2 spike protein. After injection, the viral vector delivers recombinant DNA that is decoded to mRNA, followed by mRNA decoding to become a protein. A serendipitous manufacturing error for the first 3,000 doses resulted in a half dose for those subjects before the error was discovered. Full doses were given to those subjects on second injections and those subjects showed 90% efficacy. Subjects who received 2 full doses showed 62% efficacy. A vaccine cannot be licensed based on 3,000 subjects so AstraZeneca has started a new phase 3 trial involving many more subjects to receive the combination lower dose followed by the full dose.

Johnson and Johnson (J&J) started its phase 3 trial evaluating a single dose of JNJ-78436735 in September. Phase 3 data may be reported by the end of2020. In November, J&J announced it was starting a second phase 3 trial to test two doses of the candidate. J&J’s JNJ-78436735 encodes the SARS-CoV-2 spike protein in an adenovirus serotype 26 (Ad26) vector, which is one of the two adenovirus vectors used in Sputnik V, the Russian vaccine reported to have 90% efficacy at an early interim analysis.

Sanofi and Novavax are both developing protein-based vaccines, a proven modality. Sanofi, in partnership with GlaxoSmithKline started a phase 1/2 clinical trial in the Fall 2020 with plans to commence a phase 3 trial in late December. Sanofi developed the protein ingredients and GlaxoSmithKline added one of their novel adjuvants. Novavax expects data from a U.K. phase 3 trial of NVX-CoV2373 in early 2021 and began a U.S. phase 3 study in late November. NVX-CoV2373 was created using Novavax’ recombinant nanoparticle technology to generate antigen derived from the coronavirus spike protein and contains Novavax’s patented saponin-based Matrix-M adjuvant.

Inovio Pharmaceuticals was gearing up to start a U.S. phase 2/3 trial of DNA vaccine INO-4800 by the end of 2020.

After Moderna and Pfizer-BioNTech, CureVac has the next most advanced mRNA vaccine. It was planned that a phase 2b/3 trial of CVnCoV would be conducted in Europe, Latin America, Africa, and Asia. Sanofi is also developing a mRNA vaccine as a second product in addition to its protein vaccine.

Vaxxinity planned to begin phase 3 testing of UB-612, a multitope peptide–based vaccine, in Brazil by the end of 2020.

However, emergency-use authorizations for the Pfizer and Moderna vaccines could hinder trial recruitment in at least two ways. Given the gravity of the pandemic, some stakeholders believe it would be ethical to unblind ongoing trials to give subjects the opportunity to switch to a vaccine proven to be effective. Even if unblinding doesn’t occur, as the two authorized vaccines start to become widely available, volunteering for clinical trials may become less attractive.

For most vaccines against emerging diseases, the challenge is about speed: developing and manufacturing a vaccine and getting it to persons who need it as quickly as possible. The current seasonal flu vaccine takes about 6 months to develop; it takes years for most of the traditional vaccines. That’s why once the infrastructure is in place, mRNA vaccines may prove to offer a big advantage as vaccines against emerging pathogens.
 

Early efficacy results have been surprising

Both vaccines were reported to produce about 95% efficacy in the final analysis. That was unexpectedly high because most vaccines for respiratory illness achieve efficacy of 60%-80%, e.g., flu vaccines. However, the efficacy rate may drop as time goes by because stimulation of short-term immunity would be in the earliest reported results.

Preventing SARS-CoV-2 cases is an important aspect of a coronavirus vaccine, but preventing severe illness is especially important considering that severe cases can result in prolonged intubation/artificial ventilation, prolonged disability and death. Pfizer/BioNTech had not released any data on the breakdown of severe cases as this column was finalized. In Moderna’s clinical trial, a secondary endpoint analyzed severe cases of COVID-19 and included 30 severe cases (as defined in the study protocol) in this analysis. All 30 cases occurred in the placebo group and none in the mRNA-1273–vaccinated group. In the Pfizer/BioNTech trial there were too few cases of severe illness to calculate efficacy.

Duration of immunity and need to revaccinate after initial primary vaccination are unknowns. Study of induction of B- and T-cell memory and levels of long-term protection have not been reported thus far.
 

Could mRNA COVID-19 vaccines be dangerous in the long term?

These will be the first-ever mRNA vaccines brought to market for humans. In order to receive Food and Drug Administration approval, the companies had to prove there were no immediate or short-term negative adverse effects from the vaccines. The companies reported that their independent data-monitoring committees hadn’t “reported any serious safety concerns.” However, fairly significant local reactions at the site of injection, fever, malaise, and fatigue occur with modest frequency following vaccinations with these products, reportedly in 10%-15% of vaccinees. Overall, the immediate reaction profile appears to be more severe than what occurs following seasonal influenza vaccination. When mass inoculations with these completely new and revolutionary vaccines begins, we will know virtually nothing about their long-term side effects. The possibility of systemic inflammatory responses that could lead to autoimmune conditions, persistence of the induced immunogen expression, development of autoreactive antibodies, and toxic effects of delivery components have been raised as theoretical concerns.^4-6 None of these theoretical risks have been observed to date and postmarketing phase 4 safety monitoring studies are in place from the Centers for Disease Control and Prevention and the companies that produce the vaccines. This is a risk public health authorities are willing to take because the risk to benefit calculation strongly favors taking theoretical risks, compared with clear benefits in preventing severe illnesses and death.

What about availability?

Pfizer/BioNTech expects to be able to produce up to 50 million vaccine doses in 2020 and up to 1.3 billion doses in 2021. Moderna expects to produce 20 million doses by the end of 2020, and 500 million to 1 billion doses in 2021. Storage requirements are inherent to the composition of the vaccines with their differing lipid nanoparticle delivery systems. Pfizer/BioNTech’s BNT162b2 has to be stored and transported at –80° C, which requires specialized freezers, which most doctors’ offices and pharmacies are unlikely to have on site, or dry ice containers. Once the vaccine is thawed, it can only remain in the refrigerator for 24 hours. Moderna’s mRNA-1273 will be much easier to distribute. The vaccine is stable in a standard freezer at –20° C for up to 6 months, in a refrigerator for up to 30 days within that 6-month shelf life, and at room temperature for up to 12 hours.

Timelines and testing other vaccines

Strong efficacy data from the two leading SARS-CoV-2 vaccines and emergency-use authorization Food and Drug Administration approval suggest the window for testing additional vaccine candidates in the United States could soon start to close. Of the more than 200 vaccines in development for SARS-CoV-2, at least 7 have a chance of gathering pivotal data before the front-runners become broadly available.

Testing diverse vaccine candidates, based on different technologies, is important for ensuring sufficient supply and could lead to products with tolerability and safety profiles that make them better suited, or more attractive, to subsets of the population. Different vaccine antigens and technologies also may yield different durations of protection, a question that will not be answered until long after the first products are on the market.

AstraZeneca enrolled about 23,000 subjects into its two phase 3 trials of AZD1222 (ChAdOx1 nCoV-19): a 40,000-subject U.S. trial and a 10,000-subject study in Brazil. AstraZeneca’s AZD1222, developed with the University of Oxford (England), uses a replication defective simian adenovirus vector called ChAdOx1.AZD1222 which encodes the SARS-CoV-2 spike protein. After injection, the viral vector delivers recombinant DNA that is decoded to mRNA, followed by mRNA decoding to become a protein. A serendipitous manufacturing error for the first 3,000 doses resulted in a half dose for those subjects before the error was discovered. Full doses were given to those subjects on second injections and those subjects showed 90% efficacy. Subjects who received 2 full doses showed 62% efficacy. A vaccine cannot be licensed based on 3,000 subjects so AstraZeneca has started a new phase 3 trial involving many more subjects to receive the combination lower dose followed by the full dose.

Johnson and Johnson (J&J) started its phase 3 trial evaluating a single dose of JNJ-78436735 in September. Phase 3 data may be reported by the end of2020. In November, J&J announced it was starting a second phase 3 trial to test two doses of the candidate. J&J’s JNJ-78436735 encodes the SARS-CoV-2 spike protein in an adenovirus serotype 26 (Ad26) vector, which is one of the two adenovirus vectors used in Sputnik V, the Russian vaccine reported to have 90% efficacy at an early interim analysis.

Sanofi and Novavax are both developing protein-based vaccines, a proven modality. Sanofi, in partnership with GlaxoSmithKline started a phase 1/2 clinical trial in the Fall 2020 with plans to commence a phase 3 trial in late December. Sanofi developed the protein ingredients and GlaxoSmithKline added one of their novel adjuvants. Novavax expects data from a U.K. phase 3 trial of NVX-CoV2373 in early 2021 and began a U.S. phase 3 study in late November. NVX-CoV2373 was created using Novavax’ recombinant nanoparticle technology to generate antigen derived from the coronavirus spike protein and contains Novavax’s patented saponin-based Matrix-M adjuvant.

Inovio Pharmaceuticals was gearing up to start a U.S. phase 2/3 trial of DNA vaccine INO-4800 by the end of 2020.

After Moderna and Pfizer-BioNTech, CureVac has the next most advanced mRNA vaccine. It was planned that a phase 2b/3 trial of CVnCoV would be conducted in Europe, Latin America, Africa, and Asia. Sanofi is also developing a mRNA vaccine as a second product in addition to its protein vaccine.

Vaxxinity planned to begin phase 3 testing of UB-612, a multitope peptide–based vaccine, in Brazil by the end of 2020.

However, emergency-use authorizations for the Pfizer and Moderna vaccines could hinder trial recruitment in at least two ways. Given the gravity of the pandemic, some stakeholders believe it would be ethical to unblind ongoing trials to give subjects the opportunity to switch to a vaccine proven to be effective. Even if unblinding doesn’t occur, as the two authorized vaccines start to become widely available, volunteering for clinical trials may become less attractive.

Serious neurologic complications in patients with COVID-19 are not limited to the severely ill, new research confirms.

“We found a range of neurologic diagnoses, including stroke and seizures, among hospitalized patients with COVID-19 and the majority were not critically ill, suggesting that these complications are not limited just to those patients who require ICU care or a ventilator,” study investigator Pria Anand, MD, division of neuro-infectious diseases, Boston University, said in an interview.

The study was published online Dec. 9 in Neurology Clinical Practice.
 

‘Moderately severe’ disability

For the study, the investigators reviewed the medical records of 74 adults (mean age, 64 years) who were hospitalized with COVID-19 and evaluated for neurologic conditions at Boston Medical Center, a safety-net hospital caring primarily for underserved, low-income, racial and ethnic minority populations.

The most common COVID-19 symptoms on arrival to the hospital were cough (39%), dyspnea (36%), and fever (34%). Eleven patients required intubation (15%) and 28 required some form of supplemental oxygen (38%). Thirty-four patients required intensive care (46%).

The most common neurologic COVID-19 symptoms at presentation were altered mental status (53%), myalgia (24%), fatigue (24%), and headache (18%). 

After neurologic assessment, the most common final neurologic diagnosis was multifactorial or toxic-metabolic encephalopathy (35%), followed by seizure (20%), ischemic stroke (20%), primary movement disorder (9%), peripheral neuropathy (8%), and hemorrhagic stroke (4%).

Three patients (4%) suffered traumatic brain injuries after falling in their homes after developing COVID-19.

Ten (14%) patients died in the hospital. Survivors had “moderately severe” disability at discharge (median modified Rankin Scale score of 4 from a preadmission mRS score of 2) and many were discharged to nursing facilities or rehabilitation hospitals.

“Although we do not have data on their posthospital course, this suggests that patients with neurologic complications of COVID-19 are likely to require ongoing rehabilitation, even after they leave the hospital,” Dr. Anand, a member of the American Academy of Neurology, said in an interview.

“There are a diverse range of mechanisms by which COVID-19 can cause neurologic complications,” Dr. Anand said.

“These complications can result from the body’s immunological response to the virus (e.g., Guillain-Barré syndrome, an autoimmune disorder affecting the nerves), from having a systemic severe illness (e.g., brain injury as a result of insufficient oxygenation), from the increased tendency to form blood clots (e.g., stroke), from worsening of preexisting neurologic disorders, and possibly from involvement of the nervous system by the virus itself,” she explained.

The researchers said more study is needed to characterize the infectious and postinfectious neurologic complications of COVID-19 in diverse patient populations.
 

Lingering issues

In an interview, Kenneth L. Tyler, MD, chair of neurology, University of Colorado, Denver, noted that this is one of the larger series published to date of the neurologic complications associated with COVID-19, and the first to come from a U.S. safety-net hospital in a large metropolitan area.

“Overall, the types and categories of neurological complications reported including encephalopathy (35%) and acute cerebrovascular events (~20%) are similar to those reported elsewhere,” said Dr. Tyler.

However, the frequency of stroke (~20%) is higher than in some other reports, “likely reflecting the comorbidities such as diabetes, hypertension, limited access to care [that are] present in this population,” he said.

Dr. Tyler also noted that the “relatively high frequency” of primary movement disorders, notably myoclonus, “hasn’t been particularly well recognized or described, although one of the authors has written on this in COVID-19, so perhaps there is a bit of an ‘ascertainment bias’ – as they were looking harder for it?”

Finally, he noted, it’s important to understand that all the published studies “vary tremendously in the populations they examine, so direct comparisons can be difficult.”

Also weighing in on the report in an interview, Richard Temes, MD, director, Northwell Health’s Center for Neurocritical Care in Manhasset, N.Y., said neurologic problems have been noted since the start of COVID-19 and have been well described.

“It’s common for patients to present with very nonspecific neurological complaints like confusion, disorientation, altered mental status, lethargy, but also neurological disease such as strokes, brain hemorrhages, and seizures are quite common as well,” said Dr. Temes. 

He also noted that a number of patients with COVID-19 will have “lingering effects, especially patients who are hospitalized, that can range from memory deficit, cognitive slowing, and trouble with activities of daily living and depression.

“These effects can occur with any patient who is hospitalized for a [significant] period of time, especially in the intensive care unit, so it’s hard to tease out whether or not this is truly from COVID itself or if it’s just being a survivor from a very severe, critical illness. We don’t know yet. We need more data on that,” he cautioned.

Tirzepatide, a novel subcutaneously injected drug that acts via two related but separate pathways of glucose control, produced strikingly positive effects in top-line results from the phase 3, placebo-controlled study SURPASS-1 in 478 adults with type 2 diabetes, according to a Dec. 9 press release from the manufacturer, Lilly.

The tirzepatide molecule exerts agonist effects at both the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor, and has been called a “twincretin” for its activity encompassing two different incretins. Phase 2 trial results caused excitement, with one physician calling the data “unbelievable” when reported in 2018.

SURPASS-1 enrolled patients who were very early in the course of their disease, had on average relatively mild elevation in glucose levels, and few metabolic comorbidities. They took one of three doses of the agent (5, 10, or 15 mg) as monotherapy or placebo for 40 weeks.

Julio Rosenstock, MD, said in the Lilly statement: “The study took a bold approach in assessing A1c targets. Not only did nearly 90% of all participants taking tirzepatide meet the standard A1c goal of less than 7%, more than half taking the highest dose also achieved an A1c less than 5.7%, the level seen in people without diabetes.”

Dr. Rosenstock is principal investigator of SURPASS-1 and director of the Dallas Diabetes Research Center in Texas.

The discontinuation rate in the high-dose group was 21.5% compared with less than 10% in the two lower-dose cohorts. Lilly said most of the dropouts “were due to the pandemic and family or work reasons.” The dropout rate in the placebo group was 14.8%.

These data were not included in the efficacy analysis, however, which “muddied” the analysis somewhat, one pharma analyst told BioPharma Dive.

Commenting on the new trial data, Ildiko Lingvay, MD, said in an interview: “I am very impressed with these results,” which are “unprecedented for any glucose-lowering medication that has ever been tested.”

Dr. Lingvay, of the department of internal medicine/endocrinology, and medical director, office of clinical trials management at UT Southwestern Medical Center, Dallas, was not involved in the study.

She added that the weight loss seen with tirzepatide “is equally impressive with greater than 10% of body weight loss above placebo achieved within 40 weeks of treatment and without any directed weight loss efforts.”

If the agent is eventually approved, “I am enthusiastic about the prospect of having another very powerful tool to address both diabetes and obesity,” she added.

The full results of SURPASS-1 will be presented at the American Diabetes Association 81st Scientific Sessions and published in a peer-reviewed journal in 2021.

SURPASS-1 is one of eight phase 3 studies of the drug, including five registration studies and one large 12,500-patient cardiovascular outcomes trial.
 

Tirzepatide patients lost up to 20 lb, side effect profile ‘reassuring’

In the study, patients had been recently diagnosed with type 2 diabetes (average duration, 4.8 years) and 54% were treatment-naive. Average baseline hemoglobin A1c was 7.9% and mean weight was 85.9 kg (189 pounds).

Patients started on a subcutaneous injectable dose of tirzepatide of 2.5 mg per week, which was titrated up to the final dose – 5, 10, or 15 mg – in 2.5-mg increments given as monotherapy for 40 weeks and compared with placebo. 

Treatment with tirzepatide resulted in average reductions in A1c from baseline that ranged from 1.87% to 2.07%, depending on the dose, and were all significant compared with an increase of 0.4% with placebo.

The percentage of patients whose A1c fell to normal levels (less than 5.7%) ranged from 30.5% to 51.7%, compared with 0.9% among controls, and again, was significant for all doses.

Patients treated with tirzepatide also lost weight. Average weight reductions after 40 weeks were significant and ranged from 7.0 to 9.5 kg (15-21 pounds) compared with an average loss of 0.7 kg (1.5 pounds) among patients who received placebo.

The most common adverse events were gastrointestinal-related and mild to moderate in severity, and usually occurred during dose escalation.

Dr. Lingvay said the safety data reported are “reassuring, with side effects in the anticipated range and comparable with other medications in the GLP-1 agonist class.”

And no hypoglycemic (level 2, < 54 mg/dL) events were reported, “which is impressive considering the overall glucose level achieved,” she noted.

“I am eagerly awaiting the results of the other studies within the SURPASS program and hope those will confirm these initial findings and provide additional safety and efficacy information in a wider range of patients with type 2 diabetes,” she concluded.

Dr. Lingvay has reported receiving research funding, advisory/consulting fees, and/or other support from Novo Nordisk, Eli Lilly, Sanofi, AstraZeneca, Boehringer Ingelheim, Janssen, Intercept, Intarcia, Target Pharma, Merck, Pfizer, Novartis, GI Dynamics, Mylan, MannKind, Valeritas, Bayer, and Zealand Pharma.

The percentage of patients whose A1c fell to normal levels (less than 5.7%) ranged from 30.5% to 51.7%, compared with 0.9% among controls, and again, was significant for all doses.

Patients treated with tirzepatide also lost weight. Average weight reductions after 40 weeks were significant and ranged from 7.0 to 9.5 kg (15-21 pounds) compared with an average loss of 0.7 kg (1.5 pounds) among patients who received placebo.

The most common adverse events were gastrointestinal-related and mild to moderate in severity, and usually occurred during dose escalation.

Dr. Lingvay said the safety data reported are “reassuring, with side effects in the anticipated range and comparable with other medications in the GLP-1 agonist class.”

And no hypoglycemic (level 2, < 54 mg/dL) events were reported, “which is impressive considering the overall glucose level achieved,” she noted.

“I am eagerly awaiting the results of the other studies within the SURPASS program and hope those will confirm these initial findings and provide additional safety and efficacy information in a wider range of patients with type 2 diabetes,” she concluded.

Dr. Lingvay has reported receiving research funding, advisory/consulting fees, and/or other support from Novo Nordisk, Eli Lilly, Sanofi, AstraZeneca, Boehringer Ingelheim, Janssen, Intercept, Intarcia, Target Pharma, Merck, Pfizer, Novartis, GI Dynamics, Mylan, MannKind, Valeritas, Bayer, and Zealand Pharma.

Tirzepatide, a novel subcutaneously injected drug that acts via two related but separate pathways of glucose control, produced strikingly positive effects in top-line results from the phase 3, placebo-controlled study SURPASS-1 in 478 adults with type 2 diabetes, according to a Dec. 9 press release from the manufacturer, Lilly.

The tirzepatide molecule exerts agonist effects at both the glucose-dependent insulinotropic polypeptide (GIP) receptor and the glucagon-like peptide-1 (GLP-1) receptor, and has been called a “twincretin” for its activity encompassing two different incretins. Phase 2 trial results caused excitement, with one physician calling the data “unbelievable” when reported in 2018.

SURPASS-1 enrolled patients who were very early in the course of their disease, had on average relatively mild elevation in glucose levels, and few metabolic comorbidities. They took one of three doses of the agent (5, 10, or 15 mg) as monotherapy or placebo for 40 weeks.

Julio Rosenstock, MD, said in the Lilly statement: “The study took a bold approach in assessing A1c targets. Not only did nearly 90% of all participants taking tirzepatide meet the standard A1c goal of less than 7%, more than half taking the highest dose also achieved an A1c less than 5.7%, the level seen in people without diabetes.”

Dr. Rosenstock is principal investigator of SURPASS-1 and director of the Dallas Diabetes Research Center in Texas.

The discontinuation rate in the high-dose group was 21.5% compared with less than 10% in the two lower-dose cohorts. Lilly said most of the dropouts “were due to the pandemic and family or work reasons.” The dropout rate in the placebo group was 14.8%.

These data were not included in the efficacy analysis, however, which “muddied” the analysis somewhat, one pharma analyst told BioPharma Dive.

Commenting on the new trial data, Ildiko Lingvay, MD, said in an interview: “I am very impressed with these results,” which are “unprecedented for any glucose-lowering medication that has ever been tested.”

Dr. Lingvay, of the department of internal medicine/endocrinology, and medical director, office of clinical trials management at UT Southwestern Medical Center, Dallas, was not involved in the study.

She added that the weight loss seen with tirzepatide “is equally impressive with greater than 10% of body weight loss above placebo achieved within 40 weeks of treatment and without any directed weight loss efforts.”

If the agent is eventually approved, “I am enthusiastic about the prospect of having another very powerful tool to address both diabetes and obesity,” she added.

The full results of SURPASS-1 will be presented at the American Diabetes Association 81st Scientific Sessions and published in a peer-reviewed journal in 2021.

SURPASS-1 is one of eight phase 3 studies of the drug, including five registration studies and one large 12,500-patient cardiovascular outcomes trial.
 

Tirzepatide patients lost up to 20 lb, side effect profile ‘reassuring’

In the study, patients had been recently diagnosed with type 2 diabetes (average duration, 4.8 years) and 54% were treatment-naive. Average baseline hemoglobin A1c was 7.9% and mean weight was 85.9 kg (189 pounds).

Patients started on a subcutaneous injectable dose of tirzepatide of 2.5 mg per week, which was titrated up to the final dose – 5, 10, or 15 mg – in 2.5-mg increments given as monotherapy for 40 weeks and compared with placebo. 

Treatment with tirzepatide resulted in average reductions in A1c from baseline that ranged from 1.87% to 2.07%, depending on the dose, and were all significant compared with an increase of 0.4% with placebo.

The percentage of patients whose A1c fell to normal levels (less than 5.7%) ranged from 30.5% to 51.7%, compared with 0.9% among controls, and again, was significant for all doses.

Patients treated with tirzepatide also lost weight. Average weight reductions after 40 weeks were significant and ranged from 7.0 to 9.5 kg (15-21 pounds) compared with an average loss of 0.7 kg (1.5 pounds) among patients who received placebo.

The American College of Cardiology and American Heart Association Task Force on Performance Measures have made two changes to performance measures for adults with atrial fibrillation or atrial flutter.

The 2020 Update to the 2016 ACC/AHA Clinical Performance and Quality Measures for Adults With Atrial Fibrillation or Atrial Flutter was published online Dec. 7 in the Journal of the American College of Cardiology and Circulation: Cardiovascular Quality and Outcomes. It was developed in collaboration with the Heart Rhythm Society.

Both performance measure changes were prompted by, and are in accordance with, the 2019 ACC/AHA/Heart Rhythm Society atrial fibrillation guideline focused update issued in January 2019, and reported by this news organization at that time.

The first change is the clarification that valvular atrial fibrillation is atrial fibrillation with either moderate or severe mitral stenosis or a mechanical heart valve. This change is incorporated into all the performance measures.

The second change, which only applies to the performance measure of anticoagulation prescribed, is the separation of a male and female threshold for the CHA₂DS₂-VASc score.

This threshold is now a score higher than 1 for men and higher than 2 for women, further demonstrating that the risk for stroke differs for men and women with atrial fibrillation or atrial flutter, the ACC/AHA noted in a press release.

“Successful implementation of these updated performance measures by clinicians and healthcare organizations will lead to quality improvement for adult patients with atrial fibrillation or atrial flutter,” they said.

The Centers for Disease Control and Prevention (CDC) advisory committee recommended on December 12 the recently authorized Pfizer-BioNTech COVID-19 vaccine for people age 16 and over in the United States, stating they found it was safe and effective.

The agency said it will quickly issue guidance to clinicians so they can determine when and when not to give the vaccine, and to help them communicate the risks and benefits to patients.

CDC staff gave a preview of those clinical considerations at the agency’s Advisory Committee on Immunization Practices (ACIP) meeting on December 12 and said it would be holding calls with clinicians on December 13 and 14.

The CDC will also issue guidance December 13 on how organizations can handle the workforce problems that might arise as health care workers experience side effects from vaccination.

ACIP voted 11-0, with three recusals, to recommend use of the Pfizer-BioNTech mRNA vaccine in individuals 16 years or older according to the guidelines of the Food and Drug Administration’s (FDA’s) emergency use authorization issued December 11.

The panel also voted unanimously to include the vaccine in 2021 immunization schedules. All panel members said the recommendation should go hand-in-hand with ACIP’s previous recommendation on December 1 that allocation of the vaccine be phased-in, with health care workers and residents and staff of long-term care facilities in phase 1a.

Allergies, pregnant women?

ACIP panelists said clinicians need more guidance on whether to use the vaccine in pregnant or breastfeeding women, the immunocompromised, or those who have a history of allergies.

The FDA health care provider information sheet said there is not enough data to recommend vaccinating those women or the immunocompromised, and also advises against giving the vaccine to individuals who have a history of serious allergic reaction to any component of the vaccine.

Peter Marks, MD, PhD, director of the FDA’s Center for Biologic Evaluation and Research (CBER) clarified this in a briefing on December 12, noting that women who are pregnant or lactating can make the decision in consultation with their physician. And, he said, patients with any other history of allergy should be able to safely get the vaccine.

The CDC — in its soon-to-be-released guidance — will make the same recommendations. For any woman considering vaccination, she should consider the level of COVID-19 in the community, her personal risk of contracting the virus, the risks to her or her fetus of developing the disease, and the vaccine’s known side effects, Sarah Mbaeyi, MD, MPH, a medical officer at the agency, said during the panel meeting December 12.

She added that the CDC will also urge physicians to advise women to take acetaminophen if they develop a fever after vaccination — to protect the developing fetus from fever.

Sandra Fryhofer, MD, representing the American Medical Association, commended the CDC for these recommendations. But she also called on Pfizer, the FDA, and the CDC to make data from the developmental and reproductive toxicity (DART) studies public as soon as possible.

“We really need to put those results on warp speed and get them out there to give our physicians and pregnant women more information,” said Fryhofer, an adjunct associate professor of medicine at Emory University School of Medicine in Atlanta, Georgia.

The American College of Obstetricians and Gynecologists (ACOG) will also soon release guidance for vaccinating pregnant and breastfeeding women, said Linda Eckert, MD, FACOG, an ACOG representative on the panel.

ACOG and the CDC met the morning of December 12 to discuss risks and benefits with experts in immunology, placental pathology, and vaccine kinetics, she said.

“The overall complete consensus was that we don’t see biological plausibility at this time for placental transfer of the mRNA and that we see that direct fetal exposure or the possibility of fetal inflammatory response is extremely unlikely,” said Eckert, professor of obstetrics and gynecology at the University of Washington, Seattle. “Clearly we are waiting on the data.”

A Pfizer official told the ACIP panel that preliminary data “show no indication of either developmental or reproductive toxicity,” and that the company plans to send the final DART data to the FDA at the end of December.

On the potential for allergic reactions, the CDC concurred with the FDA that the vaccine should not be given to people with a history of serious reactions. The agency added that the category should include anyone who has had a reaction to any vaccine or injectable drug product because injectables may contain the same ingredients as the Pfizer vaccine, said Mbaeyi.

The CDC will also urge clinicians to observe patients with a history of anaphylaxis for 30 minutes after vaccination and all patients for at least 15 minutes afterward.

Should teens be a special population?

At least one ACIP panel member — Henry Bernstein, DO, MHCM, FAAP — said he was concerned that backing use of the vaccine in 16- and 17-year-olds was a leap of faith, given that Pfizer had extremely limited data on this cohort.

Bernstein, professor of pediatrics at the Zucker School of Medicine at Hofstra/Northwell in Hempstead, New York, also said that systemic reactions were more common in that age group.

He argued for making the 16- and 17-year-olds a “special population” that would get specific attention and guidance for vaccination from the federal agencies and professional societies.

Bernstein said he did not want to sow any more doubts in parents’ minds about vaccination, noting that hesitancy was a growing concern. “A successful pediatric vaccination program depends on creating and sustaining parental confidence in both the safety and effectiveness of this vaccine,” he said.

Many panelists, however, noted that there has been no evidence to suggest that the vaccine is not safe or less effective in that younger age group.

Yvonne Maldonado, MD, the American Academy of Pediatrics representative on the panel, said that this age group should not be denied the vaccine as they often have essential or front-line jobs that put them at higher risk for infection.

“I am very concerned about this message being sent out that this vaccine will not be safe in children,” said Maldonado, professor of pediatrics and health research and policy at Stanford University School of Medicine in California.

“We currently have no evidence that that is the case,” she said, adding there is also no indication younger children are biologically or physiologically different in their response or safety risk than 18-year-olds.

Vaccine = hope

Committee members breathed a sigh of relief at the end of the 2-day meeting, saying that although the Pfizer vaccine is not perfect, it represents a scientific milestone and a significant advance against the continuing march of the SARS-CoV-2 pandemic.

“This vaccine and future vaccines do provide a promise for a lot of progress in the future,” said panelist Beth P. Bell, MD, MPH, clinical professor of global health at the University of Washington School of Public Health in Seattle.

Peter Szilagyi, MD, MPH, executive vice-chair and vice-chair for research at the University of California, Los Angeles pediatrics department, said, “I’m really hopeful that this is the beginning of the end of the coronavirus pandemic.”

“The need for this vaccine is profound,” said Veronica McNally, president and CEO of the Franny Strong Foundation in West Bloomfield, Michigan.

The ACIP panel also made the argument that while the at least $10 billion spent on vaccine development by the federal government’s Operation Warp Speed alone has been a good investment, more spending is needed to actually get Americans vaccinated.

The imbalance between the two is “shocking and needs to be corrected,” said Bell. “We are not going to be able to protect the American public if we don’t have a way to deliver the vaccine to them.”

The US Food and Drug Administration (FDA) has authorized Pfizer/BioNTech’s COVID-19 vaccine for emergency use in people 16 years of age and older. 

The much-anticipated emergency use authorization (EUA) of this vaccine — the first such approval in the United States — was greeted with optimism by infectious disease and pulmonary experts, although unanswered questions remain regarding use in people with allergic hypersensitivity, safety in pregnant women, and how smooth distribution will be.

“I am delighted. This is a first, firm step on a long path to getting this COVID pandemic under control,” William Schaffner, MD, professor of infectious diseases at the Vanderbilt University School of Medicine in Nashville, Tennessee, said in an interview.

The FDA gave the green light after the December 10 recommendation from the agency’s Vaccines and Related Biological Products Advisory Committee (VRBPAC) meeting. The committee voted 17-4 in favor of the emergency authorization.

Allergic reactions reported in the UK

After vaccinations with the Pfizer vaccine began in the UK on December 8, reports surfaced of two healthcare workers who experienced allergic reactions. They have since recovered, but officials warned that people with a history of severe allergic reactions should not receive the Pfizer vaccine at this time.

“For the moment, they are asking people who have had notable allergic reactions to step aside while this is investigated. It shows you that the system is working,” Schaffner said.

Both vaccine recipients who experienced anaphylaxis carried EpiPens, as they were at high risk for allergic reactions, Hewlett said. Also, if other COVID-19 vaccines are approved for use in the future, people allergic to the Pfizer vaccine might have another option, he added.

Reassuring role models

Schaffner supports the CDC Advisory Committee on Immunization Practices (ACIP) decision to start vaccinations with healthcare workers and residents of long-term care facilities.

“Vaccinating healthcare workers, in particular, will be a model for the general public,” said Schaffner, who is also a former member of the IDSA board of directors. “If they see those of us in white coats and blue scrubs lining up for the vaccine, that will provide confidence.”

To further increase acceptance of the COVID-19 vaccine, public health officials need to provide information and reassure the general public, Schaffner said.

Hewlett agreed. “I know there are a lot of people in the population who are very hesitant about vaccines. As infection disease specialists and people in public health, we are trying to allay a lot of concerns people have.”

Reassurance will be especially important in minority communities. “They have been disproportionately affected by the virus, and they have a traditional history of not being optimally vaccinated,” Schaffner said. “We need to reach them in particular with good information and reassurance…so they can make good decisions for themselves and their families.”

No vaccine is 100% effective or completely free of side effects. “There is always a chance there can be adverse reactions, but we think for the most part this is going to be a safe and effective vaccine,” said Hewlett, medical director at the Division of Disease Control and deputy to commissioner of health at the Westchester County Department of Health in White Plains, New York.

Distribution: Smooth or full of strife?

In addition to the concern that some people will not take advantage of vaccination against COVID-19, there could be vaccine supply issues down the road, Schaffner said.

Culver agreed. “In the early phases, I expect that there will be some kinks to work out, but because the numbers are relatively small, this should be okay,” he said.

“I think when we start to get into larger-scale vaccination programs — the supply chain, transport, and storage will be a Herculean undertaking,” Culver added. “It will take careful coordination between healthcare providers, distributors, suppliers, and public health officials to pull this off.”

Planning and distribution also should focus beyond US borders. Any issues in vaccine distribution or administration in the United States “will only be multiplied in several other parts of the world,” Culver said. Because COVID-19 is a pandemic, “we need to think about vaccinating globally.”

Investigating adverse events

Adverse events common to vaccinations in general — injection site pain, headaches, and fever — would not be unexpected with the COVID-19 vaccines. However, experts remain concerned that other, unrelated adverse events might be erroneously attributed to vaccination. For example, if a fall, heart attack, or death occurs within days of immunization, some might immediately blame the vaccine product.

“It’s important to remember that any new, highly touted medical therapy like this will receive a lot of scrutiny, so it would be unusual not to hear about something happening to somebody,” Culver said. Vaccine companies and health agencies will be carefully evaluating any reported adverse events to ensure no safety signal was missed in the trials.

“Fortunately, there are systems in place to investigate these events immediately,” Schaffner said.

Pregnancy recommendations pending

One question still looms: Is the COVID-19 vaccination safe for pregnant women? This isn’t just a question for the general public, either, Schaffner said. He estimated that about 70 percent of healthcare workers are women, and data suggests about 300,000 of these healthcare workers are pregnant.

“The CDC’s Advisory Committee on Immunization Practices will speak to that just as soon as the EUA is issued,” he added.

Patients are asking Culver about the priority order for vaccination. He said it’s difficult to provide firm guidance at this point.

People also have “lingering skepticism” about whether vaccine development was done in a prudent way, Culver said. Some people question whether the Pfizer vaccine and others were rushed to market. “So we try to spend time with the patients, reassuring them that all the usual safety evaluations were carefully done,” he said.

Another concern is whether mRNA vaccines can interact with human DNA. “The quick, short, and definitive answer is no,” Schaffner said. The m stands for messenger — the vaccines transmit information. "Once it gets into a cell, the mRNA does not go anywhere near the DNA, and once it transmits its information to the cell appropriately, it gets metabolized, and we excrete all the remnants."

Hewlett pointed out that investigations and surveillance will continue. Because this is an EUA and not full approval, “that essentially means they will still be obligated to collect a lot more data than they would ordinarily,” he said.

How long immunoprotection will last also remains an unknown. “The big question left on the table now is the durability,” Culver said. “Of course, we won’t know the answer to that for quite some time.”

Schaffner and Culver have disclosed no relevant financial relationships. Hewlett was an employee of Pfizer until mid-2019. His previous work as Pfizer’s senior medical director of global medical product evaluation was not associated with development of the COVID-19 vaccine.

With U.S. approval of one coronavirus vaccine likely imminent and approval of a second one expected soon after, physicians will likely be deluged with questions. Public attitudes about the vaccines vary by demographics, with a recent poll showing that men and older adults are more likely to choose vaccination, and women and people of color evincing more wariness.

Although the reasons for reluctance may vary, questions from patient will likely be similar. Some are related to the “warp speed” language about the vaccines. Other concerns arise from the fact that the platform – mRNA – has not been used in human vaccines before. And as with any vaccine, there are rumors and false claims making the rounds on social media.

In anticipation of the most common questions physicians may encounter, two experts, Krutika Kuppalli, MD, assistant professor of medicine in the division of infectious diseases at the Medical University of South Carolina, Charleston, and Angela Rasmussen, PhD, virologist and nonresident affiliate at Georgetown University’s Center for Global Health Science and Security, Washington, talked in an interview about what clinicians can expect and what evidence-based – as well as compassionate – answers might look like.
 

Q: Will this vaccine give me COVID-19?

“There is not an intact virus in there,” Dr. Rasmussen said. The mRNA-based vaccines cannot cause COVID-19 because they don’t use any part of the coronavirus itself. Instead, the Moderna and Pfizer vaccines contain manufactured mRNA molecules that carry the instructions for building the virus’ spike protein. After vaccine administration, the recipient’s own cells take up this mRNA, use it to build this bit of protein, and display it on their surfaces. The foreign protein flag triggers the immune system response.

The mRNA does not enter the cell nucleus or interact with the recipient’s DNA. And because it’s so fragile, it degrades quite quickly. To keep that from happening before cell entry, the mRNAs are cushioned in protective fats.

Q: Was this vaccine made too quickly?

“People have been working on this platform for 30 years, so it’s not that this is brand new,” Dr. Kuppalli said.

Researchers began working on mRNA vaccines in the 1990s. Technological developments in the last decade have meant that their use has become feasible, and they have been tested in animals against many viral diseases. The mRNA vaccines are attractive because they’re expected to be safe and easily manufactured from common materials. That’s what we’ve seen in the COVID-19 pandemic, the  Centers for Disease Control and Prevention says on its website. Design of the spike protein mRNA component began as soon as the viral genome became available in January.

Usually, rolling out a vaccine takes years, so less than a year under a program called Operation Warp Speed can seem like moving too fast, Dr. Rasmussen acknowledged. “The name has given people the impression that by going at warp speed, we’re cutting all the corners. [But] the reality is that Operation Warp Speed is mostly for manufacturing and distribution.”

What underlies the speed is a restructuring of the normal vaccine development process, Dr. Kuppalli said. The same phases of development – animal testing, a small initial human phase, a second for safety testing, a third large phase for efficacy – were all conducted as for any vaccine. But in this case, some phases were completed in parallel, rather than sequentially. This approach has proved so successful that there is already talk about making it the model for developing future vaccines.

Two other factors contributed to the speed, said Dr. Kuppalli and Dr. Rasmussen. First, gearing up production can slow a rollout, but with these vaccines, companies ramped up production even before anyone knew if the vaccines would work – the “warp speed” part. The second factor has been the large number of cases, making exposures more likely and thus accelerating the results of the efficacy trials. “There is so much COVID being transmitted everywhere in the United States that it did not take long to hit the threshold of events to read out phase 3,” Dr. Rasmussen said.

Q: This vaccine has never been used in humans. How do we know it’s safe?

The Pfizer phase 3 trial included more than 43,000 people, and Moderna’s had more than 30,000. The first humans received mRNA-based COVID-19 vaccines in March. The most common adverse events emerge right after a vaccination, Dr. Kuppalli said.

As with any vaccine that gains approval, monitoring will continue.

UK health officials have reported that two health care workers vaccinated in the initial rollout of the Pfizer vaccine had what seems to have been a severe allergic response. Both recipients had a history of anaphylactic allergic responses and carried EpiPens, and both recovered. During the trial, allergic reaction rates were 0.63% in the vaccine group and 0.51% in the placebo group.

As a result of the two reactions, UK regulators are now recommending that patients with a history of severe allergies not receive the vaccine at the current time.

Q: What are the likely side effects?

So far, the most common side effects are pain at the injection site and an achy, flu-like feeling, Dr. Kuppalli said. More severe reactions have been reported, but were not common in the trials.

Dr. Rasmussen noted that the common side effects are a good sign, and signal that the recipient is generating “a robust immune response.”

“Everybody I’ve talked to who’s had the response has said they would go through it again,” Dr. Kruppalli said. “I definitely plan on lining up and being one of the first people to get the vaccine.”

Q: I already had COVID-19 or had a positive antibody test. Do I still need to get the vaccine?

Dr. Rasmussen said that there are “too many unknowns” to say if a history of COVID-19 would make a difference. “We don’t know how long neutralizing antibodies last” after infection, she said. “What we know is that the vaccine tends to produce antibody titers towards the higher end of the spectrum,” suggesting better immunity with vaccination than after natural infection.

Q: Can patients of color feel safe getting the vaccine?

“People of color might be understandably reluctant to take a vaccine that was developed in a way that appears to be faster [than past development],” said Dr. Rasmussen. She said physicians should acknowledge and understand the history that has led them to feel that way, “everything from Tuskegee to Henrietta Lacks to today.”

Empathy is key, and “providers should meet patients where they are and not condescend to them.”

Dr. Kuppalli agreed. “Clinicians really need to work on trying to strip away their biases.”

Thus far there are no safety signals that differ by race or ethnicity, according to the companies. The Pfizer phase 3 trial enrolled just over 9% Black participants, 0.5% Native American/Alaska Native, 0.2% Native Hawaiian/Pacific Islander, 2.3% multiracial participants, and 28% Hispanic/Latinx. For its part, Moderna says that approximately 37% of participants in its phase 3 trial come from communities of color.

Q: What about children and pregnant women?

Although the trials included participants from many different age groups and backgrounds, children and pregnant or lactating women were not among them. Pfizer gained approval in October to include participants as young as age 12 years, and a Moderna spokesperson said in an interview that the company planned pediatric inclusion at the end of 2020, pending approval.

“Unfortunately, we don’t have data on pregnant and lactating women,” Dr. Kuppalli said. She said she hopes that public health organizations such as the CDC will address that in the coming weeks. Dr. Rasmussen called the lack of data in pregnant women and children “a big oversight.”

Dr. Rasmussen has disclosed no relevant financial relationships. Dr. Kuppalli is a consultant with GlaxoSmithKline.

Public attitudes about the vaccines vary by demographics, with a recent poll showing that men and older adults are more likely to choose vaccination, and women and people of color evincing more wariness.

Although the reasons for reluctance may vary, questions from patient will likely be similar. Some are related to the “warp speed” language about the vaccines. Other concerns arise from the fact that the platform – mRNA – has not been used in human vaccines before. And as with any vaccine, there are rumors and false claims making the rounds on social media.

In anticipation of the most common questions physicians may encounter, two experts, Krutika Kuppalli, MD, assistant professor of medicine in the division of infectious diseases at the Medical University of South Carolina, Charleston, and Angela Rasmussen, PhD, virologist and nonresident affiliate at Georgetown University’s Center for Global Health Science and Security, Washington, talked in an interview about what clinicians can expect and what evidence-based – as well as compassionate – answers might look like.
 

Q: Will this vaccine give me COVID-19?

“There is not an intact virus in there,” Dr. Rasmussen said. The mRNA-based vaccines cannot cause COVID-19 because they don’t use any part of the coronavirus itself. Instead, the Moderna and Pfizer vaccines contain manufactured mRNA molecules that carry the instructions for building the virus’ spike protein. After vaccine administration, the recipient’s own cells take up this mRNA, use it to build this bit of protein, and display it on their surfaces. The foreign protein flag triggers the immune system response.

The mRNA does not enter the cell nucleus or interact with the recipient’s DNA. And because it’s so fragile, it degrades quite quickly. To keep that from happening before cell entry, the mRNAs are cushioned in protective fats.

Q: Was this vaccine made too quickly?

“People have been working on this platform for 30 years, so it’s not that this is brand new,” Dr. Kuppalli said.

Researchers began working on mRNA vaccines in the 1990s. Technological developments in the last decade have meant that their use has become feasible, and they have been tested in animals against many viral diseases. The mRNA vaccines are attractive because they’re expected to be safe and easily manufactured from common materials. That’s what we’ve seen in the COVID-19 pandemic, the  Centers for Disease Control and Prevention says on its website. Design of the spike protein mRNA component began as soon as the viral genome became available in January.

Usually, rolling out a vaccine takes years, so less than a year under a program called Operation Warp Speed can seem like moving too fast, Dr. Rasmussen acknowledged. “The name has given people the impression that by going at warp speed, we’re cutting all the corners. [But] the reality is that Operation Warp Speed is mostly for manufacturing and distribution.”

What underlies the speed is a restructuring of the normal vaccine development process, Dr. Kuppalli said. The same phases of development – animal testing, a small initial human phase, a second for safety testing, a third large phase for efficacy – were all conducted as for any vaccine. But in this case, some phases were completed in parallel, rather than sequentially. This approach has proved so successful that there is already talk about making it the model for developing future vaccines.

Two other factors contributed to the speed, said Dr. Kuppalli and Dr. Rasmussen. First, gearing up production can slow a rollout, but with these vaccines, companies ramped up production even before anyone knew if the vaccines would work – the “warp speed” part. The second factor has been the large number of cases, making exposures more likely and thus accelerating the results of the efficacy trials. “There is so much COVID being transmitted everywhere in the United States that it did not take long to hit the threshold of events to read out phase 3,” Dr. Rasmussen said.

Q: This vaccine has never been used in humans. How do we know it’s safe?

The Pfizer phase 3 trial included more than 43,000 people, and Moderna’s had more than 30,000. The first humans received mRNA-based COVID-19 vaccines in March. The most common adverse events emerge right after a vaccination, Dr. Kuppalli said.

As with any vaccine that gains approval, monitoring will continue.

UK health officials have reported that two health care workers vaccinated in the initial rollout of the Pfizer vaccine had what seems to have been a severe allergic response. Both recipients had a history of anaphylactic allergic responses and carried EpiPens, and both recovered. During the trial, allergic reaction rates were 0.63% in the vaccine group and 0.51% in the placebo group.

As a result of the two reactions, UK regulators are now recommending that patients with a history of severe allergies not receive the vaccine at the current time.

Q: What are the likely side effects?

So far, the most common side effects are pain at the injection site and an achy, flu-like feeling, Dr. Kuppalli said. More severe reactions have been reported, but were not common in the trials.

Dr. Rasmussen noted that the common side effects are a good sign, and signal that the recipient is generating “a robust immune response.”

“Everybody I’ve talked to who’s had the response has said they would go through it again,” Dr. Kruppalli said. “I definitely plan on lining up and being one of the first people to get the vaccine.”

Q: I already had COVID-19 or had a positive antibody test. Do I still need to get the vaccine?

Dr. Rasmussen said that there are “too many unknowns” to say if a history of COVID-19 would make a difference. “We don’t know how long neutralizing antibodies last” after infection, she said. “What we know is that the vaccine tends to produce antibody titers towards the higher end of the spectrum,” suggesting better immunity with vaccination than after natural infection.

Q: Can patients of color feel safe getting the vaccine?

“People of color might be understandably reluctant to take a vaccine that was developed in a way that appears to be faster [than past development],” said Dr. Rasmussen. She said physicians should acknowledge and understand the history that has led them to feel that way, “everything from Tuskegee to Henrietta Lacks to today.”

Empathy is key, and “providers should meet patients where they are and not condescend to them.”

Dr. Kuppalli agreed. “Clinicians really need to work on trying to strip away their biases.”

Thus far there are no safety signals that differ by race or ethnicity, according to the companies. The Pfizer phase 3 trial enrolled just over 9% Black participants, 0.5% Native American/Alaska Native, 0.2% Native Hawaiian/Pacific Islander, 2.3% multiracial participants, and 28% Hispanic/Latinx. For its part, Moderna says that approximately 37% of participants in its phase 3 trial come from communities of color.

Q: What about children and pregnant women?

Although the trials included participants from many different age groups and backgrounds, children and pregnant or lactating women were not among them. Pfizer gained approval in October to include participants as young as age 12 years, and a Moderna spokesperson said in an interview that the company planned pediatric inclusion at the end of 2020, pending approval.

“Unfortunately, we don’t have data on pregnant and lactating women,” Dr. Kuppalli said. She said she hopes that public health organizations such as the CDC will address that in the coming weeks. Dr. Rasmussen called the lack of data in pregnant women and children “a big oversight.”

Dr. Rasmussen has disclosed no relevant financial relationships. Dr. Kuppalli is a consultant with GlaxoSmithKline.

Vitamin D deficiency on admission to hospital was associated with a 3.7-fold increase in the odds of dying from COVID-19, according to an observational study looking back at data from the first wave of the pandemic.

Nearly 60% of patients with COVID-19 were vitamin D deficient upon hospitalization, with men in the advanced stages of COVID-19 pneumonia showing the greatest deficit.

Importantly, the results were independent of comorbidities known to be affected by vitamin D deficiency, wrote the authors, led by Dieter De Smet, MD, from AZ Delta General Hospital, Roeselare, Belgium.

“[The findings] highlight the need for randomized, controlled trials specifically targeting vitamin D–deficient patients at intake, and make a call for general avoidance of vitamin D deficiency as a safe and inexpensive possible mitigation of the SARS-CoV-2 pandemic,” Dr. De Smet and colleagues wrote in their article, published online Nov. 25 in the American Journal of Clinical Pathology.

A search of ClinicalTrials.gov reveals there are currently close to 40 ongoing intervention trials with vitamin D in COVID-19 around the world for varying purposes, including prevention, and varying forms of treatment.
 

Consider vitamin D to prevent COVID-19 infection

With regard to the potential role in prevention, “Numerous observational studies have shown that low vitamin D levels are a major predictor for poor COVID outcomes,” noted Jacob Teitelbaum, MD, an internist who specializes in treating chronic fatigue syndrome and fibromyalgia who also has an interest in COVID-19.

“This study shows how severe a problem this is,” Dr. Teitelbaum said in an interview. “A 3.7-fold increase in death rate if someone’s vitamin D level was below 20 [ng/mL] is staggering. It is arguably one of the most important risk factors to consider.”

“What is not clear is whether vitamin D levels are acting as an acute-phase reactant, dropping because of the infection, with larger drops indicating more severe disease, or whether vitamin D deficiency is causing worse outcomes,” added Dr. Teitelbaum, who is director of the Center for Effective CFIDS/Fibromyalgia Therapies, Kailua-Kona, Hawaii.

Also asked to comment, Andrea Giustina, MD, president of the European Society of Endocrinology, said: “The paper by De Smet et al confirms what we already hypothesized in BMJ last March: that patients with low vitamin D levels are at high risk of hospitalization for COVID-19 and developing severe and lethal disease. This is likely due to the loss in the protective action of vitamin D on the immune system and against the SARS-CoV-2–induced cytokine storm.”

He said it is particularly interesting that the authors of the new study had reported more prevalent vitamin D deficiency among men than women, most likely because women are more often treated with vitamin D for osteoporosis.

The new study should prompt all clinicians and health authorities to seriously consider vitamin D supplementation as an additional tool in the fight against COVID-19, particularly for the prevention of infection in those at high risk of both COVID-19 and hypovitaminosis D, such the elderly, urged Dr. Giustina, of San Raffaele Vita-Salute University, Milan.
 

Results adjusted for multiple confounders

Dr. De Smet and colleagues looked at serum 25-hydroxyvitamin D (25[OH]D) levels in 186 patients hospitalized for severe COVID-19 infection as a function of radiologic stage of COVID-19 pneumonia as well as the association between vitamin D status on admission and COVID-19 mortality.

Cognizant of the potential for confounding by multiple factors, they adjusted for age, sex, and known vitamin D–affected comorbidities such as diabetes, chronic lung disease, and coronary artery disease.

Patients were hospitalized from March 1 to April 7, 2020 (the peak of the first wave of the pandemic) at their institution, AZ Delta General Hospital, a tertiary network hospital.

The mean age of patients was 69 years, 41% were women, and 59% had coronary artery disease. Upon admission to hospital, median vitamin D level was 18 ng/mL (women, 20.7 ng/mL; men, 17.6 ng/mL).

A remarkably high percentage (59%, 109/186) of patients with COVID-19 were vitamin D deficient (25[OH]D <20 ng/mL) when admitted (47% of women and 67% of men), wrote the authors.

“What surprises me,” said Dr. Teitelbaum, is that almost 60% “of these patients had 25(OH)D under 20 ng/mL but most clinicians consider under 50 to be low.”

All patients had a chest CT scan to determine the radiologic stage of COVID-19 pneumonia and serum vitamin D measurement on admission. Radiologic stage of pneumonia was used as a proxy for immunologic phase of COVID-19.
 

Vitamin D deficiency correlated with worsening pneumonia

Among men, rates of vitamin D deficiency increased with advancing disease, with rates of 55% in stage 1, 67% in stage 2, and up to 74% in stage 3 pneumonia.

There is therefore “a clear correlation between 25(OH)D level and temporal stages of viral pneumonia, particularly in male patients,” the authors wrote.

“Vitamin D dampens excessive inflammation,” said Dr. Teitelbaum. “In these patients with acute respiratory distress syndrome, the immune system has gone wild.”

“The study was carried out in Belgium, so there’s less sunlight there than some other places, but even here in Hawaii, with plenty of sunshine, we have vitamin D deficiency,” he added.

“More studies are needed, but I think there are enough data to suggest a multivitamin should be used to aid prophylaxis, and this is reflected in [some] infectious disease recommendations,” he noted.
